Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Trematic T-Five Beigua Maris

The Trematic T-Five Beigua Maris is lauded for its 40mm grade 5 titanium case with mixed finishes and a smooth 120-click bezel action. Reviewers highlight its attractive specifications for the price, including the La Joux-Perret G101 automatic movement, and note its well-proportioned 40mm diameter. One owner reported excellent customer service, receiving a replacement watch within a week. However, the Lumicast hour markers' glow duration and brightness are slightly below expectations, and the minute track's design can hinder precise legibility. Overall, owners and reviewers rate the Trematic T-Five Beigua Maris highly for its value and build quality, particularly the titanium case and reliable movement.

Yema Navygraf Heritage

Owners widely praise the Yema Navygraf Heritage for its comfortable 39mm wearability and faithful reissue of a 1970s model, with craftsmanship often noted as better than expected. Some owners highlight its retro look, yellow hands for legibility, and unique case design. However, multiple owners report quality control issues, including bezel free play, misalignment, and crown seating problems. Accuracy figures vary, with one owner noting it runs at +10 to +15 seconds per day, while another regulated theirs after losing 30 seconds per day, though another owner states theirs is accurate. The bezel is described as super tight to turn by one owner, despite having precise 120 clicks. Overall, owners find the Yema Navygraf Heritage a good-looking and quirky watch with notable value for its design and build.

From video reviewers

The 39mm case size and comfortable wearability are consistently praised. The in-house MBP1000 movement is mentioned as a strength by multiple reviewers. Reviewers disagree on the movement's quality, with one suggesting it should not have passed quality control while others highlight it as a positive feature.
